Why Is My Above Ground Pool Cloudy?  

 Though not a norm, pool water gets cloudy sometimes, this leaves you asking yourself, why is my above ground pool cloudy? Pool water turns cloudy due to a number of reasons, the main one being when algae start forming in your pool water. High levels of calcium hardness in your pool, insufficient free chlorine, and unbalanced pH and alkalinity are reasons that might encourage the growth of algae in your pool water. Water also remains temporarily milky after shocking.

So, Why Is My Above Ground Pool Cloudy? 

To help you find the exact problem that is making your pool water turn milky, we combined the below reasons to help you in the troubleshooting process. 

The unbalanced chlorine concentration in your pool

Chlorine is what clears your pool water of germs to make it safe to swim in. Chlorine prevents algae from developing in your pool water. Any disease-causing pathogens are killed to get make your pool healthy to swim in. 

Chlorine should be added regularly into your poll to keep the water safe. However, sometimes unpredictable events such as flooding and too high sunshine eat up the chlorine in your water. If you do not move fast to balance the chlorine levels in your eater, you might end up with bacteria and algae formation that turns your pool water cloudy.

Too high levels of chlorine on your pool water are not also safe for your health. It might also turn your water slightly opaque, however, it appreciated the earlier given reasons with time. Use a quality test kit to measure the amount of chlorine in your pool regularly. Ensure the levels are slightly below or above 3.0 ppm.

Issues with your filtration system  

Your poll filter works to clear your pool water of any debris. For a filter to achieve this, it needs to run for a good number of hours every day. Depending on the type of filter that your pool uses, the volume of water, and the activity in your pool, you might even need to run your filter continuously. 

However, for medium to small pool sizes with fewer people using it, having your filter run for up to 8 hours a day is enough to clear all the dirt and debris from your pool. 

Your filter fails or runs a few hours a day, it leaves behind dirt and particles that turn your clear pool water blurry. 

Therefore, when your pool water turns cloudy, consider checking whether your filter is working correctly and ensure it runs at least 8 hours every day.

Check for pH imbalance

The unbalanced pH value of your pool can influence your pool to turn cloudy. The pH value of your pool represents the acidic or basic level of your pool water. Too basic water, that is a pH of 8.0 and more inhibits chlorine activities in your pool water. When chlorine pauses its effect, you expect development of bacteria and subsequently algae. It is these early stages of algae that make your pool water look milky.

Too high pH means that your water is too acidic. Acidic water is corrosive and shall not go well with the eyes and skin of swimmers. Such acidic conditions in your pool water also eat up the lining of the wall of your pool. The deposits from the corrosion might also turn your pool water cloudy.  Therefore, it is good that you test your pool water pH level to a certain that it’s not the one causing a cloudy form in your water. This is especially useful when shocking your pool isn’t yielding results. 

Why Is My Above Ground Pool Cloudy – How To Clear Your Cloudy Pool

Cloudy pool water can be worrying. However, when you know how to troubleshoot the causative agent as described above, it can be easily treated.  This is how you shall clear that pool.

When your pool water turns cloudy, one, some, or all of the earlier mentioned factors might be the problem. You have to test your pool water in order to a certain of the exact problem. To test all the chemical levels in your pool, you need a quality testing kit. With this, you can test the pH, alkalinity, free chlorine levels, bromine, and even calcium levels in your pool water. 

Testing accessories come in two forms to choose from. You can decide to choose from, either a test strip or a test kit. Test kits come with reagents that you mix a sample of your pool water. When they mix, they form a color that indicates the concentration of a chemical in your pool water. 

Test strips on the other hand are very easy to use, you only have to dip them in your pool water and get the readings of chemical levels in your pool water. There are advanced technologies that support digital smart testing of your pool water.

If you realize any unbalanced chemicals, you need to balance them in order to clear your cloudy pool. If the chlorine levels in your pool keep depreciating, then you’re not using a stabilizer. Use cyanuric acid to prevent chlorine loss by UV rays from the sun. 

Repair or replace your filter 

Clear out your pool filter in case you realize any blockage. Replace any worn out parts such as cartilages to make your filter work better to clear out debris from your pool. It is good that you replace a totally worn out filter for the sake of maintaining clean clear water in your pool.
